Chinese Hypersonic missile Fractional Orbit Bombardment System

 Been a lot of talk about this.  It certainly indicates that Chinese missile engineering is good.  On the other hand I am not convinced that this weapon offers a worse threat than what we face already.  Standard ICBMs are extremely difficult to stop.  The warhead comes in at nearly orbital velocity, Mach 20 or 18,000 mph.  The warhead has a tough heat shield to prevent it melting from atmospheric friction. To shoot one down probably needs nuclear warheads on the anti missile.  

  At Raytheon many years ago I worked on the anti ballistic missile system radar.  It was a massive radar, definitely a fixed installation, no way it was ever going to be mobile.  It  was a phased array radar so it could generate multiple beams to track multiple targets.  The anti missiles had to accelerate at 100 gravities to get high enough to prevent their nuclear warheads from blowing the city they were defending away. 

In short, the new Chinese missile is impressive, but I don't see it as being all that more dangerous than standard ICBMs, of which we have a lot.  

Boeing is hurting.

 So said the Wall St Journal yesterday.  They cited a truckload of lawsuits resulting from the two crashes of brand new 737 MAX's.   They didn't talk about how the 737 MAX is selling now after the treacherous MCAS autopilot has been fixed.  How much revenue is Boeing bringing in from sales?  If it is enough to pay off the lawsuits, Boeing will survive.  If it isn't, bad things will happen.  

   They did mention that ONE Boeing employee, the senior test pilot, is in trouble with the law.  This guy convinced federal regulators that the very existence of the MCAS system did not need to be documented in any of the 737 manuals.   This seems like picking on a fairly low level employee who surely was just following direction from higher ups.  No mention of who the higher ups were. 

   The treacherous MCAS system was a band aid to make the 737 MAX fly just like the plain old 737 to avoid the cost of pilot training to fly the 737 MAX.  The 737 MAX was a plain 737 after an engine swap.  The new engines gave better fuel consumption, maybe 5% better.  With jet fuel going for $3 a gallon, and a full fuel load being a couple of 18 wheeler tank trucks, say 20,000 gallons, 5% fuel savings might be 1000 gallons, or $3000.  Nice chunk of change.  The new engines are bigger in diameter than the old ones, which meant they had to be slung somewhat lower under the wing.  Which meant that increasing the engine thrust, say for takeoff, had an increased tendency to push the aircraft's nose up.  Too much of this and the aircraft will stall, and fall like a stone.  So MCAS was supposed to give a bit of down horizontal stabilizer to counter the nose up tendency.  The two crashes of brand new 737 MAXs were blamed on the MCAS system going crazy and diving the plane into the ground.  

  The Journal piece did not mention who at Boeing, engineers or suits, OKed the MCAS design and what testing was supposed to be performed on each aircraft. 

Exit Strategy from a War??

 Only one exit strategy is acceptable, victory.  Destroy the enemy armed forces, occupy the enemy lands and capital, kill or capture enemy leaders.   Captured enemy leaders to be tried for war crimes.  If we are not prepared to pay the price to bring victory, stay out of the war. 

Down with voting machines. Up with paper ballots

 Voting machines are just desktop computers running an "I-am-a-ballot" program.  They can be hacked over the internet, while stored at city hall, while being set up for election day, and probably twenty other times and places as well.  Paper ballots, marked by the voter get checked by the voter and counted and saved in case of a recount.  Attached is a long screed against voting machines.

Colin Powell dead at 84.

 We have lost a great American.  He served his country for many many years, as a soldier, and later as advisor to presidents and secretary of state.  If he had run for president I would have voted for him. We all miss him. 

How the Fed Finances U.S. Debt.

 Wall St Journal op-ed last Thursday.  Written by Judy Shelton.

Strange article.  Never mentioned US bonds (T-bills).  First it talks about a silly plan to mint a $1 Trillion dollar platinum coin, deposit it in the Federal Reserve, and claim we are solvent.  Even if such a toy were 6 feet across, it would not be worth a TRILLION dollars.  Plus, the Fed can print all the plain old dollar bills that might be needed to redeem T-bills as they come due. 

   Then we have a strange quote from Janet Yellen.  “[It] (the platinum coin thing) is equivalent to asking the Federal Reserve to print money to cover deficits that Congress is unwilling to cover by issuing debt. It compromises the independence of the Fed, conflating monetary and fiscal policy.” 

   Wow!  I, and everyone else in America, expects the Fed to prevent a default on our T-bills by any means possible, selling more T-bills if Congress raises the debt limit, or just printing more Benjamins.  The inflationary effect of selling T-bills is about the same as for printing Benjamins.  T-bills are “near money” according to my old college economics text (Samuelson).  They are nearly as good as cash; investors who pay cash for them know that they can turn their T-bills back into cash any business day.  We run a bond market open 5 days a week, and you can sell your T-bills anytime you please and receive a cash payment within a couple of business days.

  Interesting factoid, The Fed gives the interest it earns on various things it bought to the Treasury.  This was $87 billion last year.  A nice chunk of change. 

  There are more words in the piece, but they are things everyone knows. 

Eaves vs gutter screens

 The TV has been heavily advertising gutter screens, pieces of perforated metal that fit on the top of the gutters, and let the rain water in and block out the leaves.  Cool.  Of course my house does not have gutters at all, so I don't need gutter screens.  I have nice big deep eaves, so the rain water that runs off my roof falls at a decent distance from the house and does not cause my any trouble.  

   The other benefit of good deep eaves is heating and cooling of the house.  My eaves allow the sun to shine in my south facing windows in the winter, and they block the sun in the summer to keep the house cool.  I think every house ought to have good deep eaves.
